3701:1-46-39 Calibration or reference sources containing americium-241 or radium-226: leak testing of each source.

Each person licensed under rule 3701:1-46-37 of the Administrative Code shall perform a dry wipe test upon each source containing more than 3.7 kilobecquerels (0.1 microcurie) of americium-241 or radium-226 prior to transferring the source to a general licensee under rule 3701:1-46-08 of the Administrative Code. This test shall be performed by wiping the entire radioactive surface of the source with a filter paper with the application of moderate finger pressure. The radioactivity on the paper shall be measured by using radiation detection instrumentation capable of detecting one hundred eighty-five becquerels (0.005 microcurie) of americium-241 or radium-226. If any such test discloses more than one hundred eighty-five becquerels (0.005 microcurie) of radioactive material, the source shall be deemed to be leaking or losing americium-241 or radium-226 and shall not be transferred to a general licensee under rule 3701:1-46-08 of the Administrative Code.
